Pattern description from Knockdown Knits: “There are few aspects more important in a roller girl’s uniform than the panties - especially if that uniform incorporates a skirt! No girl wants to be showing too much out on the track, but when she takes a dive and that skirt flies up, she wants something cute (with full coverage!) to be on display as well. Besides the cute factor, finding panties that provide good coverage while fitting a derby butt (all those squats and skating tend to make the butt and thighs extremely muscular) is really tricky. That is why these panties are extremely easy to adjust on the back portion. Simply add a few extra increases or a few extra rows, and voila! Panties made to fit you!”
